U'WEN R. SKELETON, 0F DETROIT, MICHIGAN, ASSIGNOR '10 CHRYSLER CORPORATION, OF HIGHLAND PARK, MICHIGAN, A COBTOBATIUN 01E DELAWARE BEAR MOTOR SUJE'PGET Application filed September 18, 1926. Serial No. 136,358.

This invention relates toa support and more particularly to a rear motor support in which a definite degree of flexibility is obtained. I

An important object of the invention is to provide a support which permits angular movement, or is yieldable under torsionalstrain, and yet one which rigidly supports the motor vertically and horizontally.

Another object is to provide such a support as a rear motor support in combination with a flexible front motor support.

Another object is to provide an inexpensive bracket made from a single stamping and w formed in such a manner as to have a strength equivalent to an expensive cast and machined bracket.

@ther objects and advantages will more fully appear from the following description m taken in connection with the accompanying drawings in which:

Fig. l is a plan view of a motor mounted in a frame by the use of my improved bracket. Fig. 2 is a front end view of the motor with 5, the frame in section.

Fig. 3 is a perspective of one of the brackets.

In the illustrated embodiment of my invention, a motor 10 has its forward end resiliently supported by a leaf spring 12. A pair of arms 14 carried by a cross member 16 of the frame 18 support the opposite ends of the spring 12 and the front end bearing housing is secured to the center of the spring 12 by means of bolts 20. The rear of the motor is supported by a pair of lateral brackets 22 constructed in accordance with my invention.

Referring to Fig. 3, showing an enlarged view of one of the brackets, an integral stamping is formed having a pair of oppositely extending flanges 24 and 26, substantially parallel and spaced by an intermediate section 28. The flange 2a is adapted to be riveted as at 30 or otherwise secured to the side frame members 18 and the flange 26 is secured to the motor arm 32 by bolts 34:.

A semi-cylindrical channel 36 is formed in the flange 24: and the intermediate section 28 connecting the two across the angle formed by the junctipn of the flange and intermediate section in such a manner as to rigidly tie the two together.

This channel gives suficient rigidity to the bracket both in a vertical and a horizontal direction and yet when a torsional strain is applied to the bracket it is resilient enough to allow one end to twist about a longitudinal axis while the other is held fast or twisted oppositely. I 1

It will be understood that by the use of such a support any twisting of the frame is not transmitted to the motor and that when the brackets are used in connection with a resilient f mounting on the front end, the motor is permitted to rock about the rear supports as a center or the frame may rock and twist without subjecting the motor to a torsional strain. I

The complete braclret is made from a single stamping and as the brackets are interchangeablethe cost has been reduced to a minimum.

While one embodiment of my invention has been illustrated and described it is not my intention to limit its scope other than by the terms of the appended claims. I

What ll claim is: 1. A resilient motor suspension compris ing in combination, a frame, a spring supporting the front end of the motor at a single point, and a 'pair of lateral supports at the rear of the motor, each having a sin 1e arm connecting the adjacent sides of sai motor and frame respectively, said arm being reinforced against flexure in horizontal and. vertical lanes and susceptible of torsional Will flexure a out an axis longitudinal thereof.

2. A resilient motor suspension comprising in combination, a motor supported between the side frame members of an automobile, a spring supporting the front end of the motor at a single point, a pair of stamped brackets having a portion extending alon said frame members and secured thereto an a portion extending inwardly from said frame members adapted tosupport the rear end of said motor, and a channel in said brackets across the angle formed by junction of said portions.

3. A resilient motor suspension comprismg a motor supported between the side frame members of an automobile, means at the forward end of said motor to permit Vertical movement thereof, means at the rear of said motor comprising a pair of brackets each having a single arm connecting the sides of said motor with the respectively adjacent side frame members, said arms being sus ceptible of torsional flexure about a longitudinal axis thereof, and means on said bracket reinforcing said arms against flexure in all other directions.

4. A resilient motor suspension comprising in combination, a motor supported between the side frame members of an automobile, a spring supporting the front end of the motor at a single point, a pair of stamped brackets having a portion extending along said frame members and secured thereto and an arm extending inwardly from said frame members adapted to support the rear end of said motor, said arm being susceptible of torsional flexure about a longitudinal axis thereof, and reinforcing means on said bracket for securing said arm against flexure in all other directions.
